This is about the fourth time I've organised for 5 of my dd's friends to come over for a get-together/film night/pizza night/sleepover etc. All the others have 2 parents at home whereas I'm on my own with 3 kids. They've all known each other 3-5 years and been friends all that time, so why doesn't anyone else step up and invite? DD has never even been to two of their houses and yet they're all bf's and love getting together. Am I missing something?
